Camber line, one section of camber line forms casting groove to the central fovea of drill bit, and another section of camber line overlap with the side of Lay Lip river triangle；Specifically
Rig structure it is as follows：
Stake machine body 1, is mainly walked by Athey wheel 3, and operation ground, stake machine body 1 are fixed on by supporting leg 2
On diagonal brace oil cylinder 4, hoist engine 5, guide rail 7 etc. are installed.Guide rail 7 is vertically arranged perpendicular to stake machine body 1.
Diagonal brace oil cylinder 4 can adjust the angle of guide rail by adjusting oil cylinder stroke, while can play a supporting role.
Hoist engine 5 can be lifted, be declined the speed change of unit head and its attached connection by steel wire rope 6 and directive wheel etc.
Case, drilling rod, drill bit；
Unit head 8 can be used as power source by motor, there is provided rotary power, and drilling rod 10 is adjusted by gearbox 9
Rotary speed.
Gearbox 9 includes the change gear mechanism of gearbox body 17 and its inside.There is gathering sill on the inwall of gearbox body 17
16, it play the guiding role.
Gear realizes speed change by gear drive, and the conversion of drilling rod realization side-circular hole motion is made by gearshift, main
To be made up of ring gear, shift cylinder, planetary gear, central gear, planet carrier and main shaft etc..
Main shaft is connected with central gear 19 by key 22-2, transmits the power of unit head, central gear 19 and planetary gear
18 engagements, planet carrier 21 connection central gear 19 and planetary gear 18, play support planetary gears；Planetary gear 18 passes through
Key 22-1 is connected with drilling rod.
Ring gear 14 can provide power by shift cylinder 15, be moved along gathering sill 16, realize entering, exit engagement
Area, when ring gear 14 into region of engagement engaged with planetary gear 18 when, planetary gear 18 can rotation again can be around central gear
19 revolution, when ring gear 14 exits region of engagement, whole gear mechanism becomes fixed shaft gear train, and planetary gear can only rotation.Pass through
The conversion of planet circular system and fixed shaft gear train, namely the conversion that side-circular hole is moved are realized in gearshift.
Hollow in drilling rod 10, upper end is connected by key with planetary gear, and obtains rotary power, and lower end is connected with drill bit.
The vertical generally spirality of drilling rod, beneficial to the discharge of drilling dregs, cross section is the Lay Lip river triangle for optimizing, and increased casting
Groove, beneficial to casting.
Drill bit 11, is connected to drilling rod lower section, is more conducive to break ground during drilling, and drill bit is existing drill bit, and its structure model can
To be selected as needed.
When drilling rod is when injection slurries are needed during drilling, slurries hole can be provided with below drill bit 11, it is possible to use
Slurries hole is whitewashed, or the unearthed bits of pump drainage from slurries hole, realizes positive and negative circulation casting mode.
Casing 12 is detachable, on guide rail, mainly plays guide rod, can be according to the form of drilling, choosing
Select circular or square casing.
The above-mentioned specific working method of rig is as follows：
During work, stake machine body 1 reaches stake holes position to be drilled by Athey wheel 3, stretches out supporting leg 2 with spud pile seat in the plane
Put, the angle of inclination of guide rail 7 is adjusted by adjusting diagonal brace oil cylinder 4.Hoist engine 5 by steel wire rope 6 be sequentially connected unit head 8,
Gearbox 9, drilling rod 10, drill bit 11, realize drilling and propose brill action.
(1) rig carry out bore circular hole operation when the course of work it is as follows：
When boring circular hole, casing 12 selects circular casing, a figures present position in such as Fig. 2 of ring gear 14, the one end of main shaft 20 with it is dynamic
Power first 8 is connected, and obtains the power of rotation, and the other end is engaged by key 22-2 with central gear 19, central gear 19 and planet
Gear 18 is meshed, meanwhile, the one end of planet carrier 21 connection central gear 19, the other end connection planetary gear 18 and drilling rod 10 rise
Supporting role.Drilling rod 10 is engaged by key 22-1 with planetary gear 18, and the section of 10 bottom of drilling rod one is drill bit 11.
During drilling, power carries out the regulation of rotating speed by way of gear is engaged, and drill bit 11 is broken ground, and soil bits can pass through
Drilling rod spiral casting.Meanwhile, it is hollow in drilling rod 10 and drill bit 11, there is slurries hole 13 on drill bit 11, so can also Selection utilization
This slurries hole 13 carries out the mode of direct circulation or reacting cycle casting.
Because planetary gear 18 is relatively fixed, and drilling rod 10 is driven to move in a circle, while in the guiding of circular casing 12
Under, the stake holes for getting out is circular hole.
(2) rig carry out bore square hole operation when the course of work it is as follows：
When boring square hole, square casing is installed in the selection of casing 12, using shift cylinder 15 along on the inwall of gearbox body 17
The propulsion ring gear 14 of gathering sill 16 to cooperation position, with planetary gear 18 engage by b figures present position in such as Fig. 2.Ring gear 14 by
Shift cylinder is positioned and fixed, and planet circular system is collectively formed with planetary gear 18, central gear 19, planet carrier 21.
During drilling, power carries out the regulation of rotating speed by way of gear is engaged, and drill bit 11 is broken ground, and soil bits can pass through
Drilling rod spiral casting.Meanwhile, it is hollow in drilling rod 10 and drill bit 11, there is slurries hole 13 on drill bit 11, so can also Selection utilization
This slurries hole 13 carries out the mode of direct circulation or reacting cycle casting.
Planetary gear 18 and the external toothing of central gear 19, according to gearratio rotation, while again with the internal messing of ring gear 14, around
Central gear 18 to revolve round the sun, also allow for drilling rod 10 not only rotation but also revolution, the section of drilling rod 10 is illustrated in figure 3 Lay Lip river three in addition
Angular, the movement locus of drilling rod just can approximately copy movement locus of the Lay Lip river triangle in wide square, so, bore
The stake holes for going out is square.
As can be seen from the above description, the application the above embodiments realize following technique effect：
Drilling rod cross section is in the form of the triangle of Lay Lip river, while realizing Lay Lip river triangle the characteristics of by planet circular system
Movement locus, using the Lay Lip river wide characteristic of triangle, reach the effect for getting out square hole, can solve on some special process will
Seek the demand of square hole stake；It is only the improvement carried out in itself to drilling rod simultaneously, and operation and conventional rig are very close to therefore effect
Rate is high；The precision of drilling is improve using the principle of Lay Lip river triangle simultaneously.
Rig utilizes mode of shifting gears, i.e.,：When ring gear is engaged into region of engagement with planetary gear, planetary gear can be certainly
Turn to be revolved round the sun around central gear again, realize the drilling to square hole；When ring gear exits region of engagement, whole gear mechanism becomes
Fixed shaft gear train, planetary gear can only rotation, drilling of the realization to circular hole；Realize planet circular system with fixed shaft gear train by gearshift
Conversion, namely realize the conversion of drilling rod side-circular hole motion；
The scope of application of rig is increased, the working space at scene is saved, the expense of equipment investment is reduced.
Although above-mentioned be described with reference to accompanying drawing to specific embodiment of the invention, not to present invention protection model
The limitation enclosed, one of ordinary skill in the art should be understood that on the basis of technical scheme those skilled in the art are not
Need the various modifications made by paying creative work or deformation still within protection scope of the present invention.
